Embodiment 1

[0047] Stable operation of the residual oil treatment unit. After the circulating hydrogen is mixed with the residual oil raw material, it passes through the residual oil hydroprocessing unit 1 and enters the reaction product gas-liquid separator 2 of the residual oil hydroprocessing unit to separate the gas from the generated oil. The gas passes through the residual oil The oil hydrotreating unit circulates hydrogen to the hydrogen desulfurization unit 3 and returns to the residual oil hydrotreating unit 1 . At the same time, the FF-14 catalyst is loaded into the hydrotreating reactor, dried, and then airtight. After the airtightness is qualified, the hydrogen partial pressure is adjusted to 14.0 MPa, the temperature is adjusted to 160°C, and sulfurized oil is introduced. After the bed temperature is stable, adjust the circulating hydrogen dehydrogenation unit 3 of the residual oil hydrotreating unit, and the circulating hydrogen containing hydrogen sulfide is introduced into...

Abstract

The invention discloses a vulcanization method of a catalyst used in a wax oil hydrotreating process. The method comprises: (1) making a residual oil hydrotreating device or a hydrocracking device operate normally; (2) equipping a wax oil hydrotreating technological device with a hydrotreating reactor; (3) adjusting the desulfurization rate of circulating hydrogen hydrogen sulfide removal equipment in the stably operating residual oil hydrotreating device or the hydrocracking technological device; (4) introducing the hydrogen sulfide-containing gas discharged from the circulating hydrogen hydrogen sulfide removal equipment in the residual oil hydrotreating or hydrocracking technological device into a wax oil hydrotreating device, and carrying out vulcanization operations on the wax oil hydrotreating device; and (5) performing vulcanization according to normal wax oil hydrotreating device vulcanization conditions till the end. The method disclosed in the invention can improve the vulcanization efficiency and reduce vulcanizing agent consumption.

Description

technical field [0001] The present invention relates to a catalyst vulcanization method for wax oil hydrotreating process, especially for the vulcanization of wax oil hydrotreating process including residue oil hydrogenation process device, high pressure hydrocracking process device and wax oil hydrotreating process device in oil refining enterprises method. Background technique [0002] Due to the slow growth of crude oil production and increasingly heavy quality, the demand for clean oil products in today's world is increasing, and the product quality requirements are becoming more and more stringent. Petroleum fraction hydrogenation technology is currently the main technology for producing clean oil products, and the preparation technology of hydrogenation catalyst is the key to hydrogenation technology. The active metal component of the prepared hydrogenation catalyst is in an oxidized state, and before the oxidized state catalyst is used in industry, its active metal n...
